Laser welding processes

Laser welding is suitable for a wide range of industries and extremely diverse applications. Leister has developed various concepts to offer the optimal solution for every application. The potential of this technique can therefore be brought to bear in every situation. Leister offers systems for contour welding (or path welding), simultaneous welding, quasi-simultaneous welding, as well as mask welding . The latest developments from Leister also advance your innovation. Radial welding joins components with rotational symmetry without moving them. Furthermore, the GLOBO clamping concepts, developed by Leister, facilitate three-dimensional laser welding for the first time.

As well as allowing 3D welding, this technique also can be used to weld large 2D areas. In 2D welding applications, there also is demand for linear welds with broader welding seams. This can be accommodated using the roller welding technique.

Special optical components known as diffractive optical elements (DOE) can be tailored to the specific laser welding process. These optical units are used with various techniques, from contour and quasi-simultaneous welding to simultaneous welding. They change the shape of a spot laser beam in order to produce a power density distribution that is suitable for the application in question.
